The leaf beetle, Chrysomela aeneicollis, lives in the Sierra Nevada Mountains of California. Scientists studying the beetles found that exposure

to high temperatures during the summer, when the eggs are laid and the

larvae are developing, causes physiological stress. The impact is on

metabolic enzymes and heat shock protein expression. One allele, pgi-4,

increased in frequency in the beetle population that was exposed to hotter,

drier summers in the Sierra Nevada Mountains.

If the temperature in the Sierra Nevada Mountains continues to increase,

what will happen to the frequency of the pgi-4 allele?

A. Increase

B. Decrease

C. Stay the same

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
